IMPROVEMENT IN GRAIN-WHEEL ARMS FOR HARVESTERS.

Specification forming part of Letters Patent No. 169,924Jdated November16, 1875; application filed July 3, 1875.

To all whom it may concern:

Be it known that I, CHRISTIAN H. SALz- MAN, of Quincy, Illinois,haveinvented certain new and useful Improvements in Grain-Wheel Arms, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The invention relates to an improved grainwheel arm, so constructed thatthe grain-wheel is always in contact with the surface of the ground; thegrain-wheel arm being provided with a ratchet and paw], so arranged thatif the cutter-bar comes in contact with any elevation, the Wheel shallstill rest upon the ground, and not be suspended above it by theelevation of the cutter-bar, the devices being also so arranged that theheight of out can be changed without the interposition of any otherdevice.

The figure is a side elevation of a device embodying the elements of theinvention.

A in the accompanying drawings represents a grain-wheel of ordinaryconstruction, for Supporting the outer end of the cutter'barv B, andmounted upon the axle D, which is fixed near the loose end of thegrain-wheel arm E, the opposite extremity of which is pivoted to theratchet F, the base of which is pivoted vertically between the cars a onthe outer end of the cutter-bar.

Thus the arm has a swinging vertical, and the ratchet a swinginghorizontal, movement. On the inside of the grain-wheel arm E, betweenthe axle D and the ratchet F, is placed the swingin g detent H, providedwith the thumb-piece b,

a rest or stop, d, being appropriately placed on the arm below thedetent, to prevent its descending too far. The tooth of the detententers the notches between the cogs e of the ratchet, the tooth and cogsbeing so relatively placed that the former Shall enter fully the notchesbetween the latter. Thus, when the tooth and detent are engaged, the armcannot swing crease or diminish the height of cut it is only necessaryto place the pawl in a higher or lower notch by operating thethumb'piece, which may be provided with a flange, h, ex-

tending over the arm, and thus obviate the I necessity for the stop 61.

It is obvious that much latitude of vertical movement is allowed thegrain-wheel arm before the tooth of the pawl will leave the notch inwhich it may be placed-hence that the operation of the device is certainand purely automatic.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The grain-wheel arm E, in combination with the detent H, ratchet F,and stop cl, Substantially as set forth.

2. The grain-wheel arm E, in combination with the pivoted segmentalratchet F and detent H, substantially as shown and described.

In testimony that I claim the foregoing improvements in grain-wheelarms, as above described, I have hereunto set my hand andseal this 17thday of June, 1875.
